What is Salmeterol?

Salmeterol is a long-acting beta-agonist bronchodilator. It is used for long-term treatment of asthma. It may also be used to prevent breathing problems in patients with night-time asthma or breathing problems caused by exercise. It may also be used for long-term treatment of chronic obstructive pulmonary disease (COPD) and other diseases.

• you are using another medicine that has a long-acting beta-agonist (eg, fluticasone/salmeterol, formoterol) in it
• you are having an asthma attack (eg, sudden severe onset or worsening of asthma symptoms such as chest tightness, cough, shortness of breath, wheezing)
• you have an unusual reaction to sympathomimetic medicine (eg, albuterol, pseudoephedrine), such as overexcitement, irregular heartbeat, or severe trouble sleeping
• if you have had a severe allergic reaction to milk protein
• if you have a history of liver problems, diabetes, heart problems (eg, fast or irregular heartbeat, heart blood vessel problems), high blood pressure, low blood potassium levels, seizures, an adrenal gland tumor (pheochromocytoma), or an overactive thyroid

How to use:

• Strictly follow your doctor's instructions
• Advert to Medication Guide if necessary
• Always activate and use this device in a level, horizontal position. Do NOT try to use a spacer device with Salmeterol.
• To prepare the device for use, open the protective foil pouch and remove the inhaler device. Hold the device in one hand. Use the thumb of the opposite hand to push the thumbgrip as far away from you as it will go. The mouthpiece will appear and snap into position.
• Hold the device in a level, flat position with the mouthpiece towards you. Use your thumb to slide the lever away from you as far as it will go. You should hear a click. The device is now ready for use.
• Do NOT close or tilt the device, play with the lever, or move the lever more than once. You may accidentally release or waste a dose.
• To use a dose of Salmeterol , hold the inhaler level and away from your mouth. Breathe out fully. Do NOT exhale into the device for any reason. Put the mouthpiece to your lips. Breathe in quickly and deeply through your mouth and hold your breath. Remove the inhaler from your mouth. Continue to hold your breath for 10 seconds or as long as possible. Then, breathe out slowly.
• Close the device when you are finished taking a dose. Slide the thumbgrip back towards you as far as it will go. The device will click shut, and the lever will return to its original position.
• Salmeterol delivers your dose as a very fine powder. Most, but not all, patients can taste or feel it. Even if you cannot feel it, do not use more than the recommended dose. If you are not sure if you are receiving your dose, contact your doctor or pharmacist.
• If you are using Salmeterol to prevent breathing problems caused by exercise, use it at least 30 minutes before you start to exercise. Do not use another dose for at least 12 hours. If you already use Salmeterol twice daily on a regular basis, do NOT take an extra dose before you exercise.
• Discard the inhaler 6 weeks after removing it from the protective foil pouch or after all the blisters have been used, whichever comes first.
• The dose indicator on the device will tell you how many doses are left. The dose indicator will read "0" when all the blisters have been used.
• Never wash the mouthpiece or any other part of the inhaler. Keep it dry and always store it in a dry place.
• Do not stop taking Salmeterol, until your doctor said so
• If you miss a dose, take it as soon as possible
• Avoid taking double or extra doses
